CAP FOR TOBACCO-PIPES.

SPECIFICATION formingpart of Letters Patent No. 499,384, dated June 13,1893.

Q Application filed May 19, 1892. Serial No. 433,572. (No model.)

To all whom it may concern.-

Be it known that I, ABRAHAM T. HARPER, of Portland, in the county ofCumberland and State of Maine, have invented certain new and usefulImprovements in Caps for Tobacco-Pipes; and Ido hereby declare that thefollowing is a full, clear, and exact description of the invention,whichwill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and toletters OfrefQrence marked thereon, which form a part of thisspecification, in which Figure 1 is a perspective view of my improvedcap detach ed from the bowl. Fig. 2 is a central longitudinal section ofsame shown in position.

The same letters refer to like parts.

My invention has relation to new and improved caps for tobacco pipes.

Its object is to provide a pipe with a cap that may be readily attachedthereto or removed therefrom, that will not deface the bowl thereby, andthat will prevent the fire or tobacco from being blown out when the windblows and from falling out when the pipe is being carried inthe pocket.

It consists of a cap composed of a rim or base having prongs adapted toextend down into the bowl and to hold said rim upon the top of the bowland a slotted cover hinged to said rim and adapted to be locked thereto,said cover having a rotary slide pivotally attached to it and said slidehaving slots therein to correspond with the slots in the cover, and incertain details of construction which will be hereinafter moreparticluarly described.

In said drawings (1 represents the bowl of a pipe; I) a rim adapted toconform to and rest upon the top of the bowl and having a central borea. Projecting out from the under side of said rim are prongs d arrangedso as to extend down into the bowl when the rim is in position. and topress against the Walls thereof. Attached to said rim in any convenientmanner is a cover e having perforations f therein and pivotally attachedto said cover is a slide g having perforations h whereby by the rotationof said slide the perforations in the slide may register with It will beevident that the slide may be on the outside of the cover or if it isnot desired to fill the pipe Without removing the cap, the

cover may be made integral with the rim.

I amaware that pipes have been made having a rim rigidly attached to thebowl and having-a perforated cover and slide and I do not claim broadlya cap having a perforated cover andgslide, but only the form hereinafterspecifically claimed.

The advantage of my improved cap is that it is readily detachable fromthe pipe and that it does not necessitate marring the bowl by rivets ornails. Moreover a cap is ordinarily not desired by smokers when the pipeis in use except when it is windy and when the pipe is put into thepocket, as it interferes with the even burning of the tobacco and soongets blackened so as to disfignre the pipe.

My device permits the cap to be used or not as desired and while it maybe used with any pipe, it is specially desirable for use with very nicepipes. The prongs may be made of flexible metal so that by bending themthey may be made to fit perfectly any size bowl.

Having thus described my invention and 7 its use, I claim-- 1. In a capfor smokers pipes, a circular rim adapted to rest on the edge of thepipe and having a central opening, flexible prongs attached to the underside of said rim, a cover hinged to said rim having perforations thereinand a rotary plate attached to said cover and having perforationsadapted to .register with the perforations in said cover, as and for thepurposes set forth.

2. Inacap for smokers pipes,a rim adapted to rest upon the edge of thepipe and having a central opening equal to the interior diameter of thepipe, flexible prongs on the under side of the rim, a cover hinged tothe top In testimony that I claim the foregoing as of said rim andadapted to be shut down my own I affix my slgnatnre in presence of oversaid opening and having perforations two witnesses.

cover, as and for the purposes set forth. NATHAN CLIFFORD.
